Sway Bar Link - Rear

This procedure covers the removal and replacement of the rear sway bar link(s) on a 1972 Ford F-100 with 302ci V8.

Warnings

Tools required

Parts

• Rear sway bar link kit (left and/or right) × 1 — Use OEM specification or aftermarket equivalent

Preparation

1. Park vehicle on level, solid ground and engage parking brake firmly
2. Place wheel chocks in front of both front wheels
3. If fasteners are rusted, apply penetrating oil to all sway bar link mounting hardware and allow to soak for 15-20 minutes

Procedure

1. 1

   Raise and support rear of vehicle
   Position floor jack under rear axle housing at the differential center section. Raise the rear of the vehicle until the rear wheels are approximately 6 inches off the ground. Place jack stands under the frame rails just forward of the rear spring hangers on both sides. Lower vehicle onto jack stands and verify stability before proceeding.
2. 2

   Locate rear sway bar and links
   Inspect the rear axle area to locate the aftermarket sway bar, which runs laterally across the axle housing. The sway bar links connect the ends of the sway bar to mounting brackets; the exact mounting points will vary depending on the aftermarket kit installed. Identify which link(s) require replacement.
3. 3

   Remove lower link fastener
   Using a combination wrench to hold the lower link bolt head, remove the lower mounting nut with a socket and ratchet. The lower connection typically attaches the link to a bracket on the axle housing. Remove the bolt, washer(s), and any bushings, noting their orientation for reassembly.
4. 4

   Remove upper link fastener
   Using a combination wrench to hold the upper link bolt head, remove the upper mounting nut with a socket and ratchet. The upper connection typically attaches the link to the sway bar end or frame bracket. Remove the bolt, washer(s), and any bushings, noting their orientation.
5. 5

   Remove old sway bar link
   Pull the sway bar link free from both mounting points. If the link is seized or binding, use a pry bar to carefully separate it from the mounting brackets. Inspect both mounting brackets for damage, deformation, or excessive wear.
6. 6

   Clean mounting surfaces
   Use a wire brush to clean the mounting surfaces on both the axle bracket and sway bar or frame bracket. Remove rust, dirt, and old bushing material to ensure proper seating of new components.
7. 7

   Install new link assembly
   Position the new sway bar link between the mounting points. Install bushings and washers in the same orientation as removed. Insert the lower bolt through the axle bracket and link, then thread the nut finger-tight. Insert the upper bolt through the sway bar or frame bracket and link, then thread the nut finger-tight.
8. 8

   Tighten link fasteners
   For rubber-bushed links, final-tighten the fasteners with the suspension loaded at approximately ride height (either on the ground or with a jack supporting the axle) to avoid preloading and prematurely damaging the bushings. Tighten both the upper and lower link fasteners. Hold the bolt head with a combination wrench while tightening the nut to the specification provided with your aftermarket sway bar kit (typically 15-30 ft-lbs for most link hardware). Tighten lower fastener first, then upper fastener. Do not overtighten as this can crush the bushings prematurely.
9. 9

   Verify link movement
   Manually push and pull on the sway bar to verify the link moves freely without binding. The bushings should compress slightly but the link should articulate smoothly through its range of motion. Check that all fasteners are secure.
10. 10

    Lower vehicle
    Raise vehicle slightly with floor jack to unload jack stands. Remove jack stands from under frame rails. Carefully lower vehicle completely to the ground.

Reassembly

1. If both left and right links were replaced, verify both are installed with matching orientation and torque
2. Test drive vehicle at low speed in a safe area and listen for any unusual noises from the rear suspension
3. Re-check fastener torque after 50-100 miles of driving

Verification

• Visually inspect both upper and lower mounting points to confirm fasteners are tight and bushings are properly seated
• Manually attempt to move the sway bar up and down - links should flex but not rattle or have excessive play
• During test drive, the vehicle should exhibit improved stability in turns with no clunking or rattling from the rear suspension
